Key Points

  • The research aims to identify potential targets and mechanisms of Gynostemma in treating depression.
  • Selected potential targets of Gynostemma intervention through databases.
  • Performed protein-protein interaction analysis, GO function analysis, and KEGG pathway enrichment.
  • Conducted molecular docking and dynamic simulations to verify interactions with key targets.
  • Identified 7 active components of Gynostemma linked to 91 targets, 85 of which relate to depression.
  • Ruvoside and Panaxadiol emerge as key active components influencing RXRA, ALB, and PTGS2.
  • Cell experiments demonstrated Gynostemma's significant inhibitory effect on depression symptoms.

Abstract

目的 探讨并验证绞股蓝干预抑郁症的潜在关联靶点与作用机制。 方法 通过数据库筛选绞股蓝干预抑郁症的潜在作用靶点,结合蛋白质互作(PPI)网络分析,基因本体(GO)功能分析和基因组百科全书(KEGG)信号通路富集分析从而得到核心信号通路;使用Auto dock软件进行分子对接,选取分子对接可视化显示结合最紧密的组合进行分子动力学模拟,使用Gromacs为模拟软件,对复合物体系进行NVT预平衡、NPT预平衡以及MD模拟;通过培养细胞实验检测绞股蓝对CORT损伤PC12细胞存活率、mtDNA拷贝数以及IL-6和IL-1β的影响,验证绞股蓝对抑郁症的抑制作用。 结果 获得绞股蓝7个活性成分,涉及91个靶点,其中与抑郁症交集靶点85个;绞股蓝抗抑郁的主要活性成分是芸香苷(Ruvoside)和人参二醇(Panaxadiol)等;主要干预靶点是RXRA、ALB和PTGS2等;KEGG结果显示,主要作用通路包括PPAR信号通路以及TRP通道的炎症介质调节等;分子对接结果显示,Ruvoside与RXRA的结合能最高,提示RXRA是绞股蓝抗抑郁的关键靶点;分子动力学模拟结果表明,Ruvoside与RXRA具有良好的结合能力。细胞实验表明,绞股蓝对抑郁症有明显的抑制作用,绞股蓝组细胞LDH释放率显著降低、mtDNA拷贝数明显增加以及IL-6水平显著降低。 结论 绞股蓝可能通过芸香苷和人参二醇等有效成分,作用于RXRA、ALB和PTGS2等靶点,从而调节PPAR信号通路和TRP通道的炎症介质,最终有助于缓解抑郁症状。
